Arable land is any land capable of being ploughed and used to grow crops. Alternatively, for the purposes of agricultural statistics, the term often has a more precise definition:
Arable land is the land under temporary agricultural crops, temporary meadows for mowing or pasture, land under market and kitchen gardens and land temporarily fallow. The abandoned land resulting from shifting cultivation is not included in this category. Data for 'Arable land' are not meant to indicate the amount of land that is potentially cultivable.
Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the reliance of crops on one set of nutrients, pest and weed pressure, along with the probability of developing resistant pests and weeds.
Intensive agriculture, also known as intensive farming, conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital, labour, agrochemicals and water, and higher crop yields per unit land area.
The British Agricultural Revolution, or Second Agricultural Revolution, was an unprecedented increase in agricultural production in Britain arising from increases in labor and land productivity between the mid-17th and late 19th centuries. Agricultural output grew faster than the population over the hundred-year period ending in 1770, and thereafter productivity remained among the highest in the world. This increase in the food supply contributed to the rapid growth of population in England and Wales, from 5.5 million in 1700 to over 9 million by 1801, though domestic production gave way increasingly to food imports in the 19th century as the population more than tripled to over 35 million.
Enclosure or inclosure is a term, used in English landownership, that refers to the appropriation of "waste" or "common land" enclosing it and by doing so depriving commoners of their rights of access and privilege. Agreements to enclose land could be either through a formal or informal process. The process could normally be accomplished in three ways. First there was the creation of "closes", taken out of larger common fields by their owners. Secondly, there was enclosure by proprietors, owners who acted together, usually small farmers or squires, leading to the enclosure of whole parishes. Finally there were enclosures by Acts of Parliament.
Dryland farming and dry farming encompass specific agricultural techniques for the non-irrigated cultivation of crops. Dryland farming is associated with drylands, areas characterized by a cool wet season followed by a warm dry season. They are also associated with arid conditions, areas prone to drought and those having scarce water resources.
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range and consume wild vegetations in order to convert the otherwise indigestible cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.
Agriculture in the Russian Empire throughout the 19th-20th centuries Russia represented a major world force, yet it lagged technologically behind other developed countries. Imperial Russia was amongst the largest exporters of agricultural produce, especially wheat. The Free Economic Society of 1765 to 1919 made continuing efforts to improve farming techniques.
Agriculture in Mongolia constitutes over 10% of Mongolia's annual gross domestic product and employs one-third of the labor force. However, the high altitude, extreme fluctuation in temperature, long winters, and low precipitation provides limited potential for agricultural development. The growing season is only 95 – 110 days. Because of Mongolia's harsh climate, it is unsuited to most cultivation.
Agriculture in England is today intensive, highly mechanised, and efficient by European standards, producing about 60% of food needs with only 2% of the labour force. It contributes around 2% of GDP. Around two thirds of production is devoted to livestock, one third to arable crops. Agriculture is heavily subsidised by the European Union's Common Agricultural Policy.
For centuries Iceland's main industries were fishing, fish processing and agriculture. In the 19th century, 70–80% of Icelanders lived by farming, but there has been a steady decline over the years and now that figure is less than 5% of the total population. It is expected that the number will continue to fall in the future. Only 1% of the total land area is under arable cultivation, confined almost exclusively to the peripheral lowland areas of the country.
Agricultural sustainability in Northern Nigeria requires flexibility in both ecological management as well as economic activity. The population densities of the rural area in this region climbed from 243 to 348 people per square kilometer between 1962 and 1991, but the land area under permanent cultivation remained approximately the same. Increasing population results in high food demand among urban and rural dwellers, areas of cultivation, and reduced soil fertility. However, there are instances where frequent agricultural practices is not associated with degradation such as in Kano and neighboring region. Even though poverty and insufficient food exists in the region, it does not affect crop yield owing to sustained efforts to produce food in response to its high demand.
Soil management is the application of operations, practices, and treatments to protect soil and enhance its performance. It includes soil conservation, soil amendment, and optimal soil health. In agriculture, some amount of soil management is needed both in nonorganic and organic types to prevent agricultural land from becoming poorly productive over decades. Organic farming in particular emphasizes optimal soil management, because it uses soil health as the exclusive or nearly exclusive source of its fertilization and pest control.
Farming systems in India are strategically utilized, according to the locations where they are most suitable. The farming systems that significantly contribute to the agriculture of India are subsistence farming, organic farming, industrial farming. Regions throughout India differ in types of farming they use; some are based on horticulture, ley farming, agroforestry, and many more. Due to India's geographical location, certain parts experience different climates, thus affecting each region's agricultural productivity differently. India is very dependent on its monsoon cycle for large crop yields. India's agriculture has an extensive background which goes back to at least 9 thousand years. In India, in the alluvial plains of the Indus River in Pakistan, the old cities of Mohenjo-Daro and Harappa experienced an apparent establishment of an organized farming urban culture. That society, known as the Harappan or Indus civilization, flourished until shortly after 4000 BP; it was much more comprehensive than those of Egypt or Babylonia and appeared earlier than analogous societies in northern China. Currently, the country holds the second position in agricultural production in the world. In 2007, agriculture and other industries made up more than 16% of India's GDP. Despite the steady decline in agriculture's contribution to the country's GDP, agriculture is the biggest industry in the country and plays a key role in the socio-economic growth of the country. India is the second-largest producer of wheat, rice, cotton, sugarcane, silk, groundnuts, and dozens more. It is also the second biggest harvester of vegetables and fruit, representing 8.6% and 10.9% of overall production, respectively. The major fruits produced by India are mangoes, papayas, sapota, and bananas. India also has the biggest number of livestock in the world, holding 281 million. In 2008, the country housed the second largest number of cattle in the world with 175 million.
Agriculture in Scotland in the early modern era includes all forms of farm production in the modern boundaries of Scotland, between the establishment of the Renaissance in the early sixteenth century and the beginning of the Industrial Revolution in the mid-eighteenth century. This era saw the impact of the Little Ice Age, which peaked towards the end of the seventeenth century. Almost half the years in the second half of the sixteenth century saw local or national scarcity, necessitating the shipping of large quantities of grain from the Baltic. In the early seventeenth century famine was relatively common, but became rarer as the century progressed. The closing decade of the seventeenth century saw a slump, followed by four years of failed harvests, in what is known as the "seven ill years", but these shortages would be the last of their kind.
Agriculture in the Middle Ages describes the farming practices, crops, technology, and agricultural society and economy of Europe from the fall of the Western Roman Empire in 476 to approximately 1500. The Middle Ages are sometimes called the Medieval Age or Period. The Middle Ages are also divided into the Early, High, and Late Middle Ages. The early modern period followed the Middle Ages.
The Norfolk four-course system is a method of agriculture that involves crop rotation. Unlike earlier methods such as the three-field system, the Norfolk system is marked by an absence of a fallow year. Instead, four different crops are grown in each year of a four-year cycle: wheat, turnips, barley, and clover or undergrass.

Agriculture in Switzerland, one of the economic sectors of the country, has developed since the 6th millennium BC and was the principal activity and first source of income until the 19th century. Framework of rural society, agriculture has as main factors the natural conditions (climate), the demographic evolution and agrarian structures. In Switzerland, it has become much diversified, despite the small size of the territory, owing to the geographical diversity of the country.
Agriculture in Ireland began during the neolithic era, when inhabitants of the island began to practice animal husbandry and farming grains. Principal crops grown during the neolithic era included barley and wheat.
